our team developing same software project on separate pcs(the networking blocked due our company rule), drug. now, our developing flow serial. when member adds feature, had wait b finish development , copy of b's project. so, here question: how conduct version control when networking not allowed? there best practices this? there git implementation allows create git repository having setting server , corresponding key, stuff that? any suggestion appreciated? you can git bundle @ anytime, , transmit single file same way getting copy of b's project. that file act git repo , not need server setup. once received other party, he/she can pull file. , missing commits. i had develop incremental bundles before . transmitting repo single file limit risk of data corruption during said transfer.

i use zsh , extend in-built cd function. i'd when call cd , changes directly , lists content of directory. function cd() { cd $1 ls . } i'd have expected code work, turns out, call cd refers function definition, resulting in infinite loop. is there work-around solve problem, apart choosing different name function? update strangely enough, worked function cd() { `echo $1` ls . } no idea why. in order use builtin commands within functions of same name, or anywhere else matter, can use builtin precommand modifier: function cd() { builtin cd $1 ls . } builtin command tells zsh use builtin name command instead of alias, function or external command of same name. if such builtin not exist error message printed. for cases want use external command instead of alias, builtin or function of same name, can use command precommand modifier. example: command echo foobar this use binary echo (most /bin/echo ) instead of zs

i have been giving hackerrank try problems require reading lines of integers arrays (slices). for many of problems, parsing code ends being larger algorithmic meat of solution. instance, case in sherlock , array any ideas on how concisely parse space-separated line of integers slice? fmt.scanf doesn't support slices , when using bufio long solutions. some requirements: you can use standard library. the solution should concise, shorter better. error checks shouldn't skipped. know input defined in hackerrank , should able cut corners, please don't, it's bad practice. it should reasonably efficient. note: parser should consume single line , not full input. you can use fmt.scanf , need keep track of values you're getting. // a.go package main import ( "fmt" "io" ) func main() { var ( next int nums []int ) { n, err := fmt.scanf("%d", &next) if err ==

i have c# app communicates on socket. want code web app can connect c# app on socket. know c# has different classes websocket , socket . questions : 1-) if use websocket javascript , can connect existing socket structure on c# or required re-code websocket ? 2-) there other performance efficent way ? a websocket connection uses socket, predefined way of framing data, while if use socket directly, can define own way of framing data, other end must know how data framed in order understand it. answering question: in javascript can connect sockets running websocket, since websocket javascript client try communicate in "websocket" way , won't understand different. however, if need javascript access regular socket, can try use intermediary proxy websockify , cannot connect directly.

for example: int main() { foo *leedle = new foo(); return 0; } class foo { private: somepointer* bar; public: foo(); ~foo(); }; foo::~foo() { delete bar; } would destructor implicitly called compiler or there memory leak? i'm new dynamic memory, if isn't usable test case, i'm sorry. yes, automatic variables destroyed @ end of enclosing code block. keep reading. your question title asks if destructor called when variable goes out of scope. presumably meant ask was: will foo's destructor called @ end of main()? given code provided, answer question no since foo object has dynamic storage duration, shall see shortly. note here automatic variable is: foo* leedle = new foo(); here, leedle automatic variable destroyed. leedle pointer. thing leedle points not have automatic storage duration, , not destroyed. so, if this: void doit() { foo* leedle = new leedle; } you leak memory allocated new leedle .

we know create "common" pointer function can example: void fun(); void (*ptr)() = fun; the name of function address function start. not need use address operator & this: void (*ptr)() = &fun; now pointer member function on contrary must use address operator. example class pointer member function ptr , function fun() must write: void(a::*ptr)() = &a::fun; why difference? it because function defined inside class. pointer member function holds "relative address" of function in class layout , have access way. in case of static, has no pointer , behaves global function , so, can access normal function pointer.

i started make twitter api. don't have twitter account, api created one. tweeted 4 times, including mentions. when use mentions_timeline this; my_mentions = api.mentions_timeline() #print(my_mentions) #output: [] after loop on my_mentions parameters text , screen_name nothing returned. what i'm doing wrong here? why it's empty list since mentioned people in tweets + how can search mentions user? there parameter in mentions_timeline() object screen_name or id ? try using new cursor object follows: api = tweepy.api(auth) mentions in tweepy.cursor(api.mentions_timeline).items(): # process mentions here print mentions.text as per twitters documentation here returns 20 recent mentions (tweets containing users’s @screen_name) authenticating user. so cannot check other users mentions using method. achieve this, have uses twitters search api. tweepy's documentation check here
